The adsorption of isobutane on a Pt(533) stepped surface has been investigated using temperature programmed desorption (TPD) and reflection absorption infrared spectroscopy (RAIRS). Isobutane exists in two monolayer states and one multilayer phase on the P ...
Bromine contg. compds. are thought to play an important role in the O3 destruction in various regions of the atm. Recent studies of atm. Br chem. suggest that HOBr is one of the important Br compds. The rapid photolysis of HOBr in daytime releases Br atoms ...
The recent development of temperature controlled scanning tunneling microscopy opened the door to a fascinating new world on the nanometer scale. The atomic scale information obtained provides unprecedented insight into the kinetics of surface phenomena su ...
An adaptation of Kubelka's general model of diffuse reflectance and diffuse transmittance of light to nonideal scattering samples is proposed. It is applied to quant. Fourier transform IR spectrometry of nondiluted surface-derivatized silica powders. Corre ...
The influence of the adipose tissue thickness on near-infrared spectroscopy to monitor the haemodynamics in muscles is investigated. It is shown by calculation of the mean optical pathlength of two-layered turbid media that the validity of the modified Bee ...
NMR spectroscopy is one of the newer spectroscopic techniques for investigating the static, dynamic and electronic structures of molecules adsorbed onto metal catalyst surfaces. We review recent progress in the application of solid-state NMR methods to the ...
The kinetics of surface processes during the growth of GaN by molecular-beam epitaxy (MBE) with ammonia as the source of reactive nitrogen is studied theoretically and experimentally. A model of surface processes is developed taking into account specific e ...
Mid-IR (MIR) spectroscopy in combination with partial least-squares (PLS) regression anal. was used to monitor the concns. of glucose, lactate, ammonia, and asparagine in situ during bioreactor cultivation of CHO/SSF3 cells. Simple PLS calibration models w ...
Boron nitride films were deposited by r.f. capacitively-coupled plasma (13.56 MHz) using two different gas mixtures: Ar-B2H6-NH3 and Ar-B2H6-N-2. In order to study the gas-phase reactions of the plasma in situ Fourier transform infrared absorption spectros ...
CO adsorption on Pd atoms deposited on MgO(100) thin films has been studied by means of thermal desorption (TDS) and Fourier transform infrared (FTIR) spectroscopies. CO desorbs from the adsorbed Pd atoms at a temperature of about 250 K, which corresponds ...
